      <p>The <codeph>fuzzystrmatch</codeph> module provides functions to determine
        similarities and distance between strings based on various algorithms.</p>
      <p>The Greenplum Database <codeph>fuzzystrmatch</codeph> module is equivalent
        to the PostgreSQL <codeph>fuzzystrmatch</codeph> module. There are no
        Greenplum Database or MPP-specific considerations for the module.</p>

        <p>The <codeph>fuzzystrmatch</codeph> module is installed when you install
          Greenplum Database. Before you can use any of the functions defined in the
          module, you must register the <codeph>fuzzystrmatch</codeph> extension in
          each database in which you want to use the functions.
